My target system use two banks of SDRAM memory and external memory for SDRAM addresses are:

               address range

Bank0     0x00400000-0x01FFFFFF - width less 28 bit

Bank1     0x04000000-0x05FFFFFF - width less 28 bit

I want use scatter DMA.

Can I use scatter DMA as:

EIEP register is an increment count and data in tap list is absolute addresses.

EIEP + data in tap list is absolute addresses = 28bit address

Am I right?
